Talk:Saturable absorption

Change in refractive index?
On this web page it is said that saturated absoption leads to a change in refractive index. If true, this would be a nice piece of information for the introduction. However, I don't understand enough of nonlinear optics to judge whether this is credible. --Dietzel65 (talk) 08:33, 27 October 2009 (UTC)

Biased References
Having a look at the references and being a researcher on a related topic I can state that ALL the references (maybe exept the last two) are absolutely irrelevant for this topic. Neither "H. Zhang" nor "D. Kouznezov" contributed in any significant way to the development or understanding of saturable absorbers and I thus suggest that one of them (User Domitori = Dimitri, like the first name of Kouznezov) or both contributed to this article. Similar things can be found in the article on disk lasers. In the present state, this article should rather be completely deleted. 134.100.111.78 (talk) 23:13, 7 April 2011 (UTC)

Pi?
In what way is pi times the fine structure constant relevant? As in'it absorbs approximately 2.3% of white light, which is π times fine-structure constant'John Pons (talk) 04:08, 24 May 2012 (UTC)
